Design, fabrication and testing of superconducting solenoid systems for high energy beam applications

Two superconducting solenoid systems have been designed, built and tested by Magnetic Corporation of America (MCA) for Los Alamos Scientific Laboratory (LASL). One solenoid system which is being used at the Meson Physics Division has a central field of 3.5 T, coil length of 91.4 cm and a horizontal room temperature warm bore of 10 cm. Another system being used at the Applied Photo Chemistry Division has a central field of 3 T, coil length 91.4 and a room temperature warm bore of 14.6 cm. The stored energy of each coil is in excess of 100 kJ. Each system provides a unique extra heavy-duty low heat loss magnet support system. The design criteria, fabrication experience and test results of the coil and cryostats are presented.
